How can PHP developers handle the issue of "Commands out of sync" error when using bind_result() method in mysqli?

When using the bind_result() method in mysqli, PHP developers may encounter the "Commands out of sync" error if they try to execute multiple queries before fetching all results from a previous query. To solve this issue, developers should use store_result() after executing a query to buffer the results before fetching them. 

// Execute the query
$stmt = $mysqli->prepare("SELECT id, name FROM users WHERE id = ?");
$stmt->bind_param("i", $id);
$stmt->execute();

// Store the result
$stmt->store_result();

// Bind the results to variables
$stmt->bind_result($userId, $userName);

// Fetch the results
$stmt->fetch();

// Close the statement
$stmt->close();
